Lately (since the gas conversion anyway) I have noticed my engine temp is about O-M on the guage (EF). I had a head repalced, coil packs, TPS, fans re wired, fair bit of engine work, but why the sudden temp increase?

Should I be worried?

weather changes towards spring/summer? its getting warmer slowly..

get a new o-ring for your thermostat, cut off the bottom plate/circle for it so it'll run cooler
